Trying to sum this up, it seems like most people got it working, and
that things are upstreamed, so I assume it is fixed in the latest
release of Ubuntu. If it is not, please file a new bug and add a comment
that references this one. Thanks!

This bug was flagged as having a patch attached. The Ubuntu Kernel
Team's preferred policy is for all patches to be submitted and accepted
into the upstream kernel before agreeing to merge them into the Ubuntu
Same problem still exists for me in Jaunty. Adding the Mitac option into
alsa-base doesn't fix it, and alsamixer still displays the same error:
ALSA lib simple_none.c:1536:(simple_add1) helem (MIXER,'Headphone
Playback Switch',0,2,0) appears twice or more
alsamixer: function snd_mixer_load
Bryce, your patches are upstreamed.
Pac, it looks like you need to modify patch_realtek.c to support the
automatic creation of non-zero index slave controls similar to what
Takashi did in sound-2.6.git commit
668b9652be33510a2a42b290dd335d34d38e2068 for patch_sigmatel.c.

This issue appears resolved on latest Jaunty for my system (Thinkpad T42
with an Intel 82801DB-ICH4 sound card).
For people on Hardy or Intrepid, I suggest you have a look at this
howto, it helped me sort out all sound problems I had:

I have the same problem with Jaunty beta (kernel 2.6.28-11) on a
Thinkpad T42 with an Intel 82801DB-ICH4 sound card.

I think bug #312302 is probably related to this.

The alsamixer -Dhw fix for me worked. Somehow PCM was changed (not
by me) to be at zero and increasing it removed the static and restored
the volume.

See also bug 315971 and bug 274884, which exacerbate this problem,
making sound quite a challenge to get functioning properly on this
chipset. (I've been able to get it working, it just takes quite a bit
of fiddling, using workarounds listed on these 3 bugs.)

Bryce, just to be sure, could you plesae run http://www.alsa-project.org
/alsa-info.sh in a similar fashion to others in this report?
Daniel, does this patch look sane? (I'm relatively inexperienced with
kernel patching and the hda code.)

** Summary changed:
- Intel 82801H sound card speakers not working

I've tried everything to get this sound working. Headphones work fine,
they're loud and clear, but speakers don't work at
I think a quirk is needed for the various 82801H cards that show this
problem, maybe something like this (untested) patch? This is my first
patch to alsa-driver so apologies if I got anything wrong.
** Attachment added: 82801h_mitac.patch
@Luke - would you mind reviewing/correcting the above patch for this
hardware?
This seems to be a fairly frequently reported problem (I found five
likely dupes, and there's a few other 82801* cards with similar
symptoms, marked as regressions since hardy).
